RE: Help. How to stop attacks on gateway/linux host.

[Yesh Sriram <ysriram () elorasoftindia com>]

Sir/Madam,
We are a small software business (mostly Java developers)  located in 
CHENNAI/INDIA. We have a machine running Linux/Redhat to
which all our computers connect for internet access through a DSL/Modem 
with static IP. We use the static IP to host demonstration for customers.

For the last 6 months our DSL bills are extremely high. We examined our 
logs and there is someone using the bandwidth from
our host every night. We can turnoff the machine but not sure if this is 
the right solution.

We have done the following (for the last three months)
- Change passwords every 3 days
- Run only http, https, ssh
- Disable ftp

But we still continue to see the nightly breaks into our host machine. 
We have no Linux expertise except as developers.
We checked out firewall software price and it's expensive, and there is 
no expert support available. Can someone
suggest a fix for this. Even a policy fix/advice would be helpfull.

We will be extremely gratefull for the support.

Regards
Yesh Sriram
